Scientists have long known that bacteria live in the human gut, working with the digestive system to break down food. But researchers have recently discovered even more far-reaching effects of the trillions of microbes living in our bodies, impacting everything from our immune systems to chronic illness. We examine the science of gut health.

GUESTS:

  • Ruth Goldstein – dietician and nutrition counselor at the Center for Integrative Medicine in Concord.
  • Dr. Allan Walker – nutrition professor at Harvard Medical School. He chaired a symposium about emerging research on probiotics last fall.
